Still working my way through White Supremacy. Apparently, in the 1600s, non-Europeans were looked down upon and considered worthy of enslavement because most of them weren’t Christians. So when enslaved Africans started converting to Christianity, the upper class had to do a lot of backing and filling to keep both their slaves and the moral high ground. And in South Africa in the 1600s and 1700s, slaves were tacitly encouraged to become Muslims, as no one saw anything wrong with keeping Muslim slaves.
